Thomas Fleetwood Willats parents were Charles Willats (1727-1768) and Mary ?
I have no marriage but the introduction of the middle name Fleetwood suggests a MARY FLEETWOOD.
Charles the son of Thomas Willats and Elizabeth Simons were Anglicans.
Mr Charles Willats I have discovered died at Spittlefields and was buried on 13th March 1768 at Bunhill Fields, London England as a Dissenter. RG4/Piece 4633/Folio 61.
